Application filed May `538, 1920. .Serial No. 384,925.

T0 all ivi/0m t may concern Be it known that we, JOHN M. Knisnn, Hnniznnfr L. GRAY, and JOHN C. KAISER, citizens of the United AStates, and residents of Rock lsland, in the county of Roc'lrlsland and State of illinois, have invented` a new and useful linprovement in `Mops, of which` the following is a full, clear, and exact description. A,

Our invention relates to improvements in iiiops, and it consists in the combinations,

constructions, and arrangements herein de-L scribed and claimed: j l

iin object of cui' inventionis toprovide a iiiop having acontinuous belt of absorbent material arranged to be guided4 in turn into operative contact with the surface of the work to be washed, immersed in a liquid, such as water or the like, and then passed through a wringing device into operative Contact with the surfacev of the work again. A. further object of our invention is4 to provide a device of the type described provided with a motor for the operation thereof, the motor being designed to beactuated by an electrical current obtained from an ordinary source of supply as by connection with electrical conducting means -usually installed in dwelling houses, wherefor ythe device inay be used wherever an electrical current is available. n,

A further object of our invention is to provide a device of the type described that is relatively simple in constructiom'easy to, operate, and not likely to get out of orderr easily. p

A further object of our invention is to provide a device of the type describedthat isthoroughly practical commercially. i j

Other objects and advantages will appear in the following speciiication, and the novel features of the invention will be particularly pointed out in the appended claim. A Our invention is illustrated iii the accompanying dra-wings, forming part of this application, in which l y Y Fig. 1 is aA side view of the device partly. broken away,

Fig. 2 is an end view of the saine, j

Fig. 3 is a detailed view of a fragmentary portion of the device,

Fig. e is a section along the line 4-4 of Fig. 1.

zIbn carrying out my invention, I provide a supporting frame or base having a bodyportion 1 and side portions 2. Oppositely rllhe drive shaft 27 adjacent to thefside portions 2 ofthe base, as bestseen in Figures 1 and dglt will be noted rthat 'the com'partmentspiareinelined ,with respect to the compartments Bffor` ay il roller purpose hereinafter described.

,supporting means fis disposed in each ofthe v compartments 3 and 4 and consists of a bear- Aing 5 in which is inserted oiic end of a shaft 8. The bearings areinaiiitained in the coiiimounted onthe shafts 8. It is to be noted that'a stem` QeXtends upwardly from each bearing 5, being formed integrally therewith or` rigidly 'f secured thereto,nand `that the upper end of thestem 9 is slidable in" a p b oss 10 which projectsy laterally from the side 2.- A. cap plate, 11, which .is adjustably secured to the boss 41() by means ofthe set screw 12, prevents lateral ydisplacementy of Ldisposed Compartment-svy and are provided 5 lpartiiients byplates 6. yRollers l' are rigidly the stein 9. The. set'screw12is screwed into'openings in the plate llan'd the boss 10 f and is rigidly carried by the latter. Bearings are normallyfpressed downwardly by meansof lspriiigs13 but may be forced' upwardly whentheosurfaces yofthe rollers?` `which,normally eXtendvbelow the bottom ofi .theside portions 2,y encounter inequalities in the surfacebeingltraversed. v

A `pairv of ,wheels 14 are mounted vupon shaftsl.

sides 2 adjacent one `end thereof. A third wheel 16 ismounted upon a shaft which has its endsouriialled inthe forks 17 of an upright rod 18.'4 The latte-r is pivoted riii a bracket 19, which is secured to the otherend ofthe base ,1 means of bolts20, the rod 18 being maintained in position by means `of a nut orwashei1 21 ywhich is carried at A.the

upper end thereof. 1 f,

We mount a tank .22` upon the base l? se- The latter are journalled in the curing the same thereon by means ofL fasten l ing plates 23, which are secured to the base bybolts 24.k Surmountingthe tankL 22 and resting` onthe cover therefor isa base or ysupport `25 for motor 26. The ylatter lis itil) n of thelniotor`26lpro jects slightlybeyoiid one sider of the. tank and has a gear '29 rigidlyL secured'thereto.

The gear 29 is in mesh with an intermediate gear 30 which is mounted'for rotation on" a' stubshaft' 31. The latter 1S $691113@ lll. ai

vertical support 32 which is formed integrally with the base 25 or may be formed separately and secured thereto. The intermediate gear 30 is in mesh with athird gear 34 which is carried at the end of a shaft 35. The shaft 35has its ends journalled in the side portions 39 of the motor base 25. A roller 36 is mounted upon the shaft 35 for rotation therewith and is consequently driven by the motor 26. A gear case 28 encases the gears 29, 30, and' 34, Vas shown, being removably secured in place in any suitable manner. The gears l29, 30, and 34L are ,stepped in size', as shown, and are preferably rawhide gears, since it is desirable that durable, elastic, and noiseless gears be provided. It will, ofcourse, be understood that the base 25 is formed suitably to permit operation of the roller 36 and also the operation of a roller38, which is positioned at a spaced distance from the roller 36; ,being mounted for rotation with a shaft 40 which has its ends journalled in rlhe bearings 41 are slidably disposed in key-w'ays'42 which are provided in the side portions 39 of the base 25. The position of the bearings 41 may be varied by vmeans of keys 44 which lare screwed in each end'of the side portions 39, as clearly shown in Fig. 3.

Additional guiderollers 45 are positioned for free rotation within the tank 22. A continuous belt 46 which has a width slightly less than that of the tank 22, is passed around thev various rollers, as best seen in Fig. l. The belt 46 is formed of any suitable, durable, absorbent material and is the immediate means employed in accomplishing the functions ordinarily accomplished with ay mop. Y

From the foregoing description of the various kparts 'of the device, the operation thereof may be readily understood.l The tank 22 is kept partly filled with water. It is obvious that when the device is moved over a surface, the operation of the rollers 7 and 45'will cause the belt 46 to contact with the Vsurface of the floor or the like, to Vthen be passed through the water in the tank 22, then fed between the rollers 36 and 38 Awhich are operated in thesame manner as the rollers in a wringer. The moistenedbelt 46 then contacts with the floor or the like (again, eectually cleansing the surface thereof. The roller 45 and the roller 7, carried .by the inclinedrecess 4, also act as automatic tightening means for the belt 36. An outlet 47 is provided to permit emptying of the tank 22 when the contents'thereof has become filled with sediment vwrung from the belt 46 by actionv of the rollers 36 and '38. A

' ing or establishing a circuit, as desired.

'are provided for connecting the electrical It is, of course, to be un-v conducting means in the handle 48 with an electrical fixture, such as is usually installed in a house. A push button 52 is positioned in the handle 48 to control the operation of the motor while the device is being operated. 4Cover plates 53 and 54 are positioned, as shown, being designed to cover the ends of the tank 22 and to enhance the appearance of the device. The portion of the tank not covered by the base 25 is covered by a closure 55 which is hinged at 56. The closure 55 has a knob or handle 57 which provides a convenient means for raising the same when it isdesired to refilly the tank 22.

My improved mop may be operated at a slight costl and provides a'practical means for thoroughly, easily and expeditiously performing the work that prior to myinvention required considerable time and labor.

One of the advantages of the device lies in the fact that the moisture content of the belt 46 which contacts with the floor may be regulated, thereby preventing the marring of polished surfaces while insuring the e'ectual cleansing of the same.

We claim: n

A mopping device comprising `a frame, frame supporting rollers yieldingly carried by said frame, the ends ofeach supporting roller adapted tomove independently of the movement of the other end of they roller, whereby said yrollers are adapted to move toward or away from the frame so as to contact with the supporting surface irrespective of the contourrof the surface, a mopping memberarranged to travel over said rollers to contact with the supportingsurf'ace, and another supporting'roller adapted to move angularly with .respect to the other rollers whereby said roller is adapted to take up the
